Nice. How much power does one of those put to the ground?

How fast is your rig with that in there? like 0-60 time/top speed, and also the towing capacity? Also, Seems like a cool build! Subscribed.

I know the benefits to the OM606 but the om617 fits in perfect..no body mods or anything needed & is very very similar to the original 4.0.

Obviously the 617 is lacking in the performance department, but with the Ip cranked, 12psi, alda deleted, & a a w112? intake & 3" exhaust they can go pretty darn good. Why choose the 606 over the 617?

There was a lot of numbers going on in that last post..... Lol

I totally agree with your comments, this one is a one off I am doing for myself. The next ones will have the 617 engine for the reasons you stated. I had this engine from another project and wanted to use it not knowing all the trouble it was going to be. But after building Street Rods for a living for 30 years before getting into the 4x4 field this is a piece of cake.
There is a web site www.superturbodiesel.com that has some killer modified 617 engines that would blow the doors off of a small block chevy.

great job , but i drive 300-350 for one tank in my 4.0 5speed

how many miles do you think you can drive per tank ?
in my opinion not less than 450-500 !! with 20 G tank

Well to be honest the Om617 is a tractor motor lol..more so than our 4.0's. Its a 5cly, and with the stock injector pump it will make around 250ftlbs max..after that you run out of fuel. At that point its time for meth injection or to have Myna? mod the IP (injector pump) for around 1500. And that will get you as much power you want! I prefer meth injection as it will make more power, keep the motor clean (think steam cleaning) & lower EGT's & IAT's.
Anyway they can achieve mid-high 20's...don't expect that much in a lifted jeep however I'd say 22-24mpg would be achievable..basically same jeep, with a 4.0 would probably get 18mpg, while the Om617 would get 20-25mpg. The benefits become alternative fueling & diesel being cheaper in most states..They call the Om617 a million mile motor. And I believe theres threads floating around where people have posted pictures of 900K

For me, I'd love to do the swap, it would better fit my expo rig & make it more appocalyse friendly...think bio-fuels!
But the 4.0 will go 500K, it will degrade & loose performance at that mileage, more so than a diesel would. In my case I would gain maybe 5mpg or so over the gas motor. Diesel is about the same & often more than gas in California. And it would cost me more to get a setup going to produce Bio-fuel. So I would probably be loosing in the end!
I choose to build a 4.2L high compression, high efficiency motor...I'm using the old 3.8L crank, will have a .0038" quench height, 9.8:1 comp, ported head, stock 87-95 single pattern cam advanced a few degrees to make it come alive sooner.

Its installed -8 degrees, or 8 degrees retarded. It comes alive around 2500rpm & holds power to around 6200rpm before it falls off. Advancing the cam to say -4 would make it come alive around 2000rpm hopefully & fall off around 5500rpm. We only rev to 5300rpm max, so it makes perfect since to do so
The 96-01 guys got the dual pattern cam, it comes on really strong from 1000-4000rpm..then falls flat around 4400rpm. I prefer the 87-95 cam that stays strong to 6200rpm because it can be advanced & you get the best of both worlds..redline power & low end torque!


Currently with a 2.5" OME lift, around 3" actual, 31's AT's & 3.55 gears with a ax15/np231. I'm cruising around 1950rpm at 65mph. 242k original motor, a few mods to help mileage & I'm getting 18mpg city & 22-24mpg city. I coast, watch lights ahead of me to catch them on green & draft when safely possible! So I wouldn't gain much!
